Yes, more pixels to draw requires more graphics power draw the picture and more VRAM store the graphics data en route to the GPU cores. Only problem is that the OP's cousin does not even have a monitor currently and wants a 19-22" monitor. Hence, he will, until his supply of funds expands, require only 1920x1080 pixels for the GPU core to draw maximum in the near future. For an estimated two years, as according to his opening post, he does not have or will not commit the funds to have such a luxurious multi-monitor setup or any other upgrade.
Lower end cards do have options with more VRAM as well.
The GPU-acceleration has
documented evidence in which once you go above a Radeon HD 7750 or GTX 650.
Total time to complete = time for GPU-dependent tasks to complete+time for CPU-dependent tasks to complete. Number of hard drives and system RAM also affect time for a task to complete, but with his budget, he is limited in those areas too to the bare minimum of 8 GB and 1 disk.
However, these GPU gains in time MUST offset that approximately halved or slightly less than halved performance of the FX-4130 compared to the i5. Any CPU task is going to take approximately twice as long.
As far as I can see, whatever configuration is the final, it will be less than ideal for hardcore Photoshop. The matter here is to help him pick out the best from the limited funds he has. Your case will hold IF the tasks he performs are the gpu-limited tasks and not those that are CPU-limited, RAM-limited, or the hard drive slowing down everything.
Would switching to AMD free up enough funds for a 2-4gb 128bit vram bus gddr5 card and a second monitor though?
May be worth checking. Especially if this rig is not intended to be upgraded any time soon.
Here in the US a 2gb 128bit vram bus gddr5 card like the geforce gtx 650 is $120, the 7770 can be had for $135, you could drive 2 or 3 monitors with either of these, and monitors can be had pretty cheap.
Both have a 128bit bus, but have fast gddr5 memory, so the impact is lessened. To go to 3 or 4 gb of memory the cost goes over $200 pretty quick. . .If you insist on gddr5 memory, which is what makes the 128 bit bus not suck, so it should be non negotiable in my opinion.

Something to consider when looking at cpu's, the Intel I5 4430 is not often benchmarked, and it is not equivalent to other intel cpu's in the line.

AMD motherboards with integrated graphics support hybrid crossfire, which would allow the onboard gpu to assist an AMD primary GPU. . . Although in practice I think it works out a little wonky, like you have to have a specific low level card to activate it. Something to consider.
Also I am not sure how the implementation of this feature works with the socket FM2 trinity APU's. However it may be favorable for such a tight budget.

I have no experience running such hybrid gpu configs personally though.
I decided to see what kind of value you could get with AMD. 8 core piledriver with 8bg corsair 1600ddr3 cl9 ram, 2gb gddr5 GeForce 650, 2 Dell S2240L 21.5 inch LED Backlit LCD Monitors, case power supply hard disk and optical disk drive for Rs. 57660, less if you go for the six core cpu and or cheaper motherboard.

So I think you could have a more productive workstation by going with AMD, definately.
